dassi
dassi is an AI agent that runs in your browser's sidebar: give it a task in natural language or demonstrate it once, and it will click, fill in forms, navigate pages, and handle documents for you — and you can save tasks as workflows that run on a schedule.
About dassi
dassi is an AI browser agent that runs in your browser's sidebar (a Chrome extension). You can give it tasks in natural language, or demonstrate what you want once and let it learn; it will then click buttons, fill in forms, navigate between pages, handle documents, and work with the accounts you are already logged into and the AI model of your choice. For tasks that need to be repeated, you can save them as workflows that run on a schedule instead of being triggered manually each time. According to official documentation, the agent itself runs on your machine: dassi runs entirely inside the browser as a Chrome extension, with no backend servers processing your browsing data; when you send a message, the prompt and page content are sent only to the AI provider you choose (hosted credits go through the hosted gateway, while a self-supplied OpenAI key connects directly to OpenAI). Before visiting a new domain or performing actions on sensitive pages, dassi first presents a plan and waits for your explicit approval, and you can stop it at any time. According to the official comparison page, what sets dassi apart from general AI assistants is that the work happens in your own browser and accounts, and it is designed for repetitive work — it keeps workflows, schedules, approval rules, context for specific websites, and a history of every run. It supports models such as Claude, GPT, and Gemini.

Compare before choosing
According to the official comparison page: Axiom.ai builds bots through no-code step construction, while dassi learns tasks from natural language or from watching you perform an action once, and re-reads the page on every run; Axiom.ai offers a 2-hour free allowance, after which runtime plans range from $15 (5 hours) to $250 (250 hours).
According to the official comparison page: Genspark runs tasks on cloud computers and bills by credits, while dassi works in your own browser with the accounts you are already logged into; BYOK starts at $10/month; Genspark offers a free tier (about 100 credits per day), Plus at $24.99/month ($19.99 billed annually), and Pro at $249.99/month.
According to the official comparison page: Perplexity Comet's Control browser is said to now consume credits and can only be used inside Comet; dassi works on Chrome, Edge, or Brave with your own logged-in accounts; the Perplexity Comet browser is free, with Pro at $20/month (4,000 one-time credits) and Max at $200/month.

Performs browser actions for you
Clicks buttons, fills in forms, types text, navigates between pages, and manages multiple tabs on your behalf.
Automates multi-step workflows
Chains multi-step tasks together, such as doing research across tabs, filling out application forms, or extracting data; reusable tasks can be saved as workflows and run on a schedule.
Writing and editing
Drafts emails, summarizes articles, rewrites text, and composes messages.
Document handling
Works directly in the browser with Excel, Word, Google Sheets, Google Docs, PDF, and other common file formats.

Plan approval and privacy controls
Presents a plan and waits for approval before visiting a new domain or performing sensitive page actions; the agent runs on your machine, and official documentation states that browsing history, passwords, and personal data are not sent.
Pros
- The agent runs locally in your browser; official documentation states that browsing history, passwords, and personal data are not sent, and page content is sent only to the AI provider you choose
- Supports bringing your own API key (BYOK), letting you freely choose models such as Claude, GPT, and Gemini
- Supports saving repetitive tasks as workflows that run on a schedule, with run history and approval rules retained
- Requires your explicit approval of a plan before visiting new domains or performing sensitive actions, and can be stopped at any time
- Works directly in the browser with common file formats such as Excel, Word, Google Sheets, Google Docs, and PDF
Cons
- Available only as a Chrome extension, so it requires a browser environment.
- When using hosted credits, requests are relayed through a hosted API gateway to AI providers such as Anthropic and Google; only when you bring your own OpenAI key do requests connect directly to OpenAI. Users with strict requirements about data transmission paths should note this difference.
